Zirconium oxide is a high-performance ceramic material known for its mechanical strength, thermal stability, and chemical resistance. It is widely used in industrial applications, including ceramics, coatings, refractories, and technical components.

Chemical and Physical Properties

• Density: ~5.68 g/cm³ (monoclinic)

• Melting Point: ~2,715 °C

• Boiling Point: ~4,300 °C

• Solubility: Insoluble in water and most organic solvents; soluble in hydrofluoric acid

• Crystal Structure: Monoclinic (room temperature), tetragonal or cubic at higher temperatures

• Thermal Conductivity: Low (useful for thermal insulation)

• Electrical Properties: Acts as an ionic conductor at high temperatures (used in fuel cells)

Applications

• Advanced Ceramics: Used in engineering ceramics for wear resistance, high temperature stability, and toughness.

• Thermal Barrier Coatings: Applied to turbine blades and engine parts to resist heat and corrosion.

• Refractory Materials: Utilized in crucibles, linings, and foundry applications due to high melting point.

• Dental and Medical Devices: (Note: not mentioned further as per your preferences).

• Catalyst Supports: Functions as a support for metal catalysts in chemical reactions.

• Optical Components: Used in coatings and polishing applications due to high refractive index and hardness.

Safety

This chemical does not meet GHS hazard criteria for 100% (23 of 23) of all reports. Pictograms displayed are for < 0.1% (0 of 23) of reports that indicate hazard statements.

Handling and Storage

• Handling: Avoid generating or inhaling dust. Use under local exhaust or fume hood when handling fine powders.

• Storage: Store in a tightly sealed container in a dry, cool, well-ventilated area. Keep away from incompatible materials such as strong acids and bases.

Environmental Considerations

Zirconium oxide is chemically inert and not classified as environmentally hazardous in typical applications. Avoid releasing fine particles into water systems or air in large quantities.
